HOW: Start a squat position with your knees bent and hips slightly hinged forward. Push into the ground and jump as high as you can creating the triple extension of your feet, knees, and hips. As you land go in directly into the squat position again and perform the prescribed amount of reps or time.
FEEL: You should feel all of your lower body muscles working as you squat and explode up into a forceful jump.
COMPENSATION: Keep your chest up. Jump and land in the same position.
